I take issue with the idea that Edge could be a disruptor - it's just another chromium/blink browser. The flaws with the browser are fundamental - not something a different interface and Microsoft telemetry can fix.
The only alternatives are non-chromium based browsers - so that's Apple with safari/Webkit and Mozilla with Firefox/gecko.
Apple is hardly the champion of open standards - it forces all browsers to use Webkit on IOS because it's app store too much of a money spinner to allow users free access to the internet. They might buy digital things and apple not be able to snoop and block it so they get their 30%.
So realistically the only options are Firefox derivatives or a 3rd party coming along and using Webkit. But Webkit is problematic due to the level of control Apple has, in the same way Google has control of Blink/Chromium. And the open source KDE project Khtml that both Apple and Google forked from has died, leaving Gecko as the only independent Web engine available.
I don't see anything coming along to disrupt Google at the moment.
I use Firefox myself. I also use Librefox which is a decent spin. It would be good to see an ecosystem of gecko browsers - a gecko browser similar to Brave or Vivalidi might be able to disrupt things. It's also kinda wasteful that any contributions all these chromium based projects currently make upstream also ultimately benefit Google.
